How to kill a protein

For decades scientists have been looking closely at how our cells make proteins. But the inverse is equally important: how cells kill them.

Scientists gain new insights into protein disposal

Cells have a sophisticated system to control and dispose of defective, superfluous proteins and thus to prevent damage to the body. Dr. Katrin Bagola and Professor Thomas Sommer of the Max Delbrück Center for Molecular Medicine ...

Scientists discover new way protein degradation is regulated

(Phys.org) —Proteins, unlike diamonds, aren't forever. And when they wear out, they need to be degraded in the cell back into amino acids, where they will be recycled into new proteins. Researchers at Rockefeller University ...

Stem cells: Keeping differentiation in check

Researchers at the A*STAR Institute of Medical Biology (IMB) have discovered a critical checkpoint protein that controls when human embryonic stem cells (hESCs) begin to differentiate.

Watching the cogwheels of the biological clock in living cells

Our master circadian clock resides in a small group of about 10'000 neurons in the brain, called the suprachiasmatic nucleus. However, similar clocks are ticking in nearly all cells of the body, as demonstrated by the group ...

Immunoproteasome crystal structure determined

Like a shredder, the immunoproteasome cuts down proteins into peptides that are subsequently presented on the cellular surface. The immune system can distinguish between self and nonself peptides and selectively kills cells ...
